Clearly the airport is the last place you should be stomping your feet and arguing with staff

but confiscating a really really bloody expensive liquid because the SEE THROUGH BOTTLE says 150ml and it’s clearly half empty - therefore under 100mls purely because the label says 150mls?!

And she didn’t throw it in the bin she put it on the shelf in front of her. Robbed, I was bloody robbed

AIBU - the rule is the liquid amount; not the amount the bloody bottle says

(Yes I know the rules)

(yes I really do know the rules)

(yes I know you aren’t allowed to take more than 100mls through)

(why did I try then? - because the rule says you can’t take more than 100mls through - not yoh can’t take a bottle marked at 150mls which is clearly half empty through)

(no I didn’t check my baggage)

(because it wasn’t worth the cost for a two night stay and hang luggage was fine)

(yes I know this is a first world problem and some people can’t fly anywhere)

And do you think 100.05ml makes any difference to anything?

Yes. The limit is 100ml.

It’s like saying “oh officer I was only 1 over the limit”, the limit is the limit.

That's not the point. The point is the rule is 100ml and the people enforcing the rules have to do so swiftly and easily. They can't be being asked to make judgement calls on whether a larger bottle contains 100ml, slightly more or slightly less.

itslikecakesbutitsnotcakes · 25/05/2026 08:30

I’ve been a frequent flyer (usually 2x a week (domestic, Europe and Ultra long haul) for nearly 20 years.
I’ve known for all that time that it’s containers of no more than 100ml. Very few airports have done away with it so I just work on that basis and never been caught out

NamelessNancy · 25/05/2026 08:25

Notmyreality · 25/05/2026 08:09

Yeah no. Totally irrelevant.

What do you suggest then? Moving to a system of roughly/ballpark numbers? Just eyeballing containers?

Flying on A380 or not an extra .05 ml is unlikely to make a difference but if you're limiting liquids by numbers you need a line somewhere and there can't be wriggle room, otherwise you start to get "creep", or just inconsistences.

That's when the arguments would really start:

".....but last week your nice colleague let me take 110 ml through...where's your supervisor?"?

Fundamentally even the most frequent users of airport security get caught out occasionally, maybe by loading up bags in a rush or being caught out by airport rules.....it's a PITA when it happens but you have to accept it - no point in blaming security staff ot worse still thinking they've picked on you so they get to go home with a freebie..

0.05 x the number of passengers (potentially circa 500 on an A380)? Possibly!

lt’s like taking an exam. If you fail by just 1% or 2%, you fail.

Yeah no. Totally irrelevant.

We know what the rules are. And we know what they are for that’s why we obey them. The airports have these rules in response to a terrorist threat and if we want to fly we obey the rules.
In airports which still have the old scanners the container can’t be more than 100ml that’s it. It then follows that the liquid in the container will be 100ml or less.
I was caught out because I didn’t realise my cleanser bottle was 125ml, they took it out. I knew it was my mistake.

My local airport we can now carry 2L containers and liquid. However the last time I travelled the return airport still had the old liquid rules so I had to pack with that in mind which is annoying but it’s just the way it is.

The rules change during the year because the airport has upgraded their scanners. There isn’t a conspiracy to rob you of your half used bottle of expensive whatever it was

Spot on!

So the upshot is multiple airports have different rules.

Some allow 2lt through, some don’t allow mini travel bottles unless they are pre-marked (not at home) as 100mls or less.

Some airports change their rules throughout the year

You might leave one airport with one set of rules and travel through another with a different set of rules.

The rules are there to keep us safe, except the rules are all different.

Nobody really knows what the rules are for but we all obey them anyway

MrsVBS · 25/05/2026 07:41

YABU, the rules quite clearly say that it’s 100ml been if it’s a bigger bottle that’s half empty, if you were so bothered by something being confiscated because it was expensive you would have checked and double checked.

Notmyreality · 25/05/2026 07:38

Brickiscool · 23/05/2026 18:31

Because half empty is subjective. Was it really 75ml or could it have been two thirds or three fifths. Was it 99.5ml or 100.05ml.

Rules make these things clear!

And do you think 100.05ml makes any difference to anything?

StarlightLady · 25/05/2026 07:30

Monty36 · 24/05/2026 12:43

I suspect it does get binned or destroyed. You seem to think she will have it for herself. Given it was half empty even less likely it would be used. She will have no idea what is in it.

It does get destroyed. There is no guarantee that what it says on the container label and the contents ate the same thing.

LuckyHazelFox · 25/05/2026 07:21

I was too stupid to read the rules and had to pay £11 quid to get my brand new bottle of Chanel No5 body spray back when I returned from my holiday. Now that is obscene.

“Some airports may allow you to take liquid in
containers that hold up to 2 litres of liquid”

Why?? Why is this even a thing then. Just make the rule and stick with it

It depends on the type of security scanners which the airport have.

Would you prefer to get blown out the sky with a bomb made from liquids. It was narrowly averted.

Somebody tried to blow up a shoe twenty years ago.

CrikeyMajikey · 25/05/2026 05:45

Perk of the job, keeping the good stuff. I think I’d have a little chuckle spraying something lovely I’d confiscated from an obnoxious traveller.

tilypu · 25/05/2026 05:38

"OP, take no notice of the holier than thou lecturing posters. Everyone has messed up at security at least once, then they won't do that again!"

I admit, I have messed up at security - there was a bottle in my hand luggage that I had forgotten about. You know what I didn't do? Get "pissed off" (ops words) enough to write about it online. Or even do anything other than apologise to the security person, and then get on with my day once it was resolved.

The issue isn't that op messed up. The issue is that op refuses to acknowledge that and continues to blame the airport.

JustMyView13 · 24/05/2026 13:01

To add insult to injury, some airports allow you to store oversized liquids and collect on your return.

yoshigizzit · 24/05/2026 12:39

Lol-ing at expensive bottle of oil pocketed by the staff, I very much doubt they kept half a bottle of oil, who would even know oil was expensive?

Yeah, I can just imagine all the staff heading home with armfuls of other people's half-used toiletries at the end of a shift!

RedToothBrush · 24/05/2026 10:10

Manchester Airport has fully installed the new 2l scanners. They have briefly implied the 2l rule. Then they reversed them.

As I have already said.

Do not assume that new scanners equals more than 100mls. It does not.

Read the rules for the individual airport instead of repeating bollocks like this.

Eh? 🤪 She said exactly what you said.

Fucking hell, is the sun not shining where you are?

Monty36 · 24/05/2026 12:43

Cablestitches · 23/05/2026 17:29

But she didn’t throw it into the big box of confiscated liquids did she. She tucked it away on the shelf in front of her

What even happens to all the stuff they confiscated? It gets binned? Bullshit it does

I suspect it does get binned or destroyed. You seem to think she will have it for herself. Given it was half empty even less likely it would be used. She will have no idea what is in it.

Yes, if you want to get on the plane you have to follow the rules, all of which are very easily available online (if your head isn’t so far up your bum you can’t access it).

Besafeeatcake · 24/05/2026 12:20

Ummm no. Your oil didnt get stolen. You attempted to break the rules, got caught and it got confiscated.

There are rules in places because terrorist attempted to blow up planes by mixing liquids.

You can stomp your feet all you want but you were wrong.

This
Entirely on you

NamelessNancy · 24/05/2026 12:26

Isn't it obvious that they wouldn't judge <100ml by just eyeballing bigger bottles?
